Unable to attach the geometry file
 

Hi
I have imported a .stp file for 3D geometry in Design Modeler and generate successfully and saved, then I extracted the data as .agdp. now I am going to mesh the geometry but it fails to load the file in mesh system! the error is :
''unable to attach the geometry file'' and the meshing window is gone then,

This .stp file for geometry is ok as it was used by another person and worked successfully.

Would you kindly help me to solve this problem.
